Hi Marek,

I tried your config on a stock v2.6.38. The resulting image is written to
eeprom at 0x80000 address and I started via bootm 0x80000.
Decompressing is ok but then it hangs again, the cpu is still in IRQ-mode
at the same address 0xffff0018 :-(..

CCing linux arm kernel.

Try one more thing ... check if the kernel with my config forces command line and 
if so, check if there's a mem= option. If it's missing, add mem=128M at 0xa0000000, 
for some reason, I recently had issues with passing kernel params from 
bootloader.

I also had issues with 256MB module, dunno if it's your case. FTTB, use only 
128MB until it's solved. It's work in progress.

greetings
Bas

Hi Marek,

currently I'm running the latest u-boot from the git archive on the

vpac270

module, no problems so far. The latest kernel
is giving me problems when I load it via u-boot. The uncompression goes
well but somewhere in the boot proces it hangs. The
debugger shows that the ARM is in IRQ mode and the PC is at 0xffff0018,
executing a 0xea0000 instruction. Somehow it looks
like the vector table is not initialized.

I met this too.

In the Voipac directory I don't see any patches so I assume that the
vanilla kernel is good enough. I also disabled in the board

initialization

all the pheriperal initialization
except for the serial port but no luck so far. Do you have any

suggestions

quoted

for me to look for?

Try attached config, I already discussed this with voipac people, they
met the
same issue.
